Hand Facts: News about hands!

In 2004 Chinese researchers present a new approach to study the hand lines for biometric purposes. They applied a mathematical model on hand prints and were able to identify six types of  palmar crease variations – based on the core characteristics of the three ‘major palmar lines’. Recently, in line with the Chinese research a new more advanced (PIC) model was introduced which e.g. describes 21 types of major hand line variations which are displayed in ‘a family tree of the major hand line types’: see the picture above.

Interestingly, the new study reports e.g. about a correlation between the palmar lines and intelligence (IQ): left hand vs. right hand asymmetries appear to be involved, plus a lower prevalence of MPA’s – such as the simian line & Sydney line).

NOTICE: The three major palmar lines concern:

– The ‘radial longitudinal crease’, in palmistry a.k.a. the ‘life line’;
– The ‘distal transversal crease’, in palmistry a.k.a. the ‘heart line’;
– The ‘proximal transveral crease’, in palmistry a.k.a. the ‘head line’.
